Two-Level Factor Analysis of Morphometric Characters of Honeybees Population Sampled (Apis mellifera L.) in Turkey

Abstract

genellikle hiyerrarşik yapıdadır. Bu yapı içerisinde bal arıları farklı bölgelerde ve farklı lokasyonlarda koloniler halinde yaşarlar. Bu nedenle gözlemler arasında bağımsızlığın düşünülmesi gerçekçi değildir. Çünkü örneklenen birimler aynı bakım koşullarını ve aynı çevresel etkileri paylaşmazlar. Bu tür hiyerarşik yapıdaki verilerin analizi için çok seviyeli faktör analiz modeli önerilebilir. Bu araştırmada modeli bal arılarının morfometrik ölçüm sonuçlarına uygulayarak çok seviyeli faktör analizini basamak basamak anlatan bir model sunulmuştur. Beklenildiği gibi kanat, bacak, ve damar karakterlerinden oluşan üç factor yapısı oluşmuştur. Sonuçlar, koloniler arası ve koloni içi morfometrik faktör yapısının beklenen ile uyumlu olduğunu göstermektedir
